</blockquote><h4><a name = "tag_002_001_182">&nbsp;</a>DESCRIPTION</h4><blockquote>
These functions add information to the current or specified window at the
current or specified position, and then advance the cursor.  These
functions perform wrapping.  These functions perform special-character
processing.
<ul>
<p>
<li>
If <i>wch</i> refers to a spacing character, then any previous character at
that location is removed, a new character specified by <i>wch</i> is placed at
that location with rendition specified by <i>wch</i>; then the cursor advances
to the next spacing character on the screen.
<p>
<li>
If <i>wch</i> refers to a non-spacing character,
all previous characters at that location are preserved, the non-spacing
characters of <i>wch</i> are added to the spacing complex character, and
the rendition specified by <i>wch</i> is ignored.
<p>
</ul>
</blockquote><h4><a name = "tag_002_001_183">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion, these functions return OK.  Otherwise, they return
ERR.
</blockquote><h4><a name = "tag_002_001_184">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
